Configuring the System for Multiple Unit Operation
Verify all DC and AC connections. Check Xanbus network connections and ensure that
terminators are installed at devices at each end of the network. The simplest system
includes a Xanbus SCP, the two multi-unit-configured Conext SW inverter/chargers, and
two Xanbus terminators.
For both units to operate in multiple unit configuration, a Master and Slave have to be
assigned. The default out-of-box configuration for all Conext SW inverter/chargers is
Master which causes a conflict the first time the system is powered up. The installer will
need to change configuration on one of the inverter/chargers to Slave mode.
To configure the system for multiple unit configuration:
1. Apply DC power to both inverter/chargers.
Power up order has no impact. Because there are now two Master units in the
system, the SCP will detect an F71 fault, a “system configuration fault”.
2. From the SCP System Status screen, press Enter. The Select Device screen
appears.
3. Select the inverter to configure as a Slave unit from the list, then press Enter.
4. Bring up the Advanced Settings screen by pressing Enter, Up, and Down arrow
buttons all together.
5. Select Advanced Settings and press Enter. The Advanced Settings screen
appears.
6. Scroll down to select Multi Unit Config.
At this point all devices in the system will be automatically placed in standby mode.
All three LEDs on the inverter to be configured will start flashing
7. Select Invtr Mode and press Enter.
8. Select Slave and press Enter.
9. Press the Exit button repeatedly until the System Status screen appears.
NOTE: The only situation in which the Slave may shut down the Master inverter is
during fault detection conditions such as high or low battery voltage, overcurrent, or
over-temperature conditions. Both inverters will auto reset after a fault detection
condition has been cleared. The exception is that an overcurrent condition will generate
a shutdown for both inverters that will require a manual restart of the system.
